Someone on another forum put a new Yammy Raptor fuel cock on his Zephyr 550.
34mm bolt-hole spacing?
Yamaha fuel cock: 5LP-24500-01-00 (~$20 at ronayers.com).
5LP-24500-00-00 looks to be almost identical (this one is superseded by the -01-00 unit).
There may be other Yamaha fuel valves.

If the spacing on your 81 1100 is 34mm, then it should work. I've been riding around w a disabled vacuum petcock for a few weeks, but now even it is leaking. If a new diaphragm kit doesn't work (already purchased, doh), then I'm switching to a manual.
PS: a clear plastic Tropicana orange juice jug is handy for collecting the fuel when the bike is parked in the garage... saves the fuel for reuse & cuts way down on the gasoline fumes.
I modified mine. I thought I posted pics/how to here. I just searched, guess not.
Basically, I stared at it till I figured out what had to be done, filled the holes with that two part gas tank repair, the lever you turn I modified. It was far more simpler than I thought when I started. It doesn't leak a drop. I left a nearly full tank, off the bike, sitting in the sun while I did something, I could smell gas around the cap vent, and my modded valve was bone dry.
After done, I took a file and flat filed where the filters were. Had to make a gasket that lined up with the holes, all very simple, total cost was bout 5.00 and an hour.

If you eyeball it, you'll see where the reserve feeds to the fuel "out".
Plug the vacuum line out with that tank repair. You look at the lever that controls res/fuel etc you'll need to remove a tab allowing it to move past its stop. Like I said, 5.00 and mine hasn't leaked a drop in 5 months. Hmm, seems I didn't upload to an offsite, but did it here, still cant find the photos..dangit.

Also, a vac petcock from a ZG1000 Concours may be a viable option as well.

Here's something I just stumbled across. This conversion kit might work on many KZ models as the Concours has the same diaphragm cover assy & tap lever o-ring. It looks kinda nifty, but I haven't taken the time to compare the Concours part to the KZ.

Martin, I would love to try out this kit if I thought it would fit my bike. That would be better than my prime/on and on and reserve /off setup I have now.

The bolt hole spacing of the aftermarket fuel valve is listed as 34mm. same as the 81 csr.
The 82-83 650-csr bolt hole spacing should be 44mm & the 82-2005 police bikes should also be 44mm.
The Yamaha raptor fuel valve should be 34mm. oem & made in Japan. ~$30.
there are several different raptor fuel valves.
Stuff to check when getting a non-stock fuel valve. extension of fuel valve body below the tank. --- some extend down, some are tucked up close to the tank. pickup tube length. fuel port O.D. country of origin --- Japan, Taiwan, china.
